Looking for Allen&Heath Qu32 console's service manual

I'm looking for A&H Qu32 service manual. I have got a unit where probably the DAC has failed - I can see the signal going in on the meter but there is no signal coming out from any outputs.
I have done all sorts of troubleshooting before opening up the unit. Just want to locate where the DAC chip is at.
Thanks in advance for the help.
